<para
>Proxies are programs running on a computer that acts a server on the network you are connected to (whether by modem or other means). These programs receive &HTTP; and &FTP; requests, retrieve the relevant files from the internet, and pass them on to the client computer that made the requests.</para>

<para
>When you have configured a proxy, &HTTP; and/or &FTP; requests are re-routed through the computer that is acting as a proxy server. However, you can also select specific hosts which should be contacted directly, rather than through the proxy server. If you are on a local network, for example, access to local hosts probably doesn't need to go through a proxy server.</para>

<para
>You should only need to configure a proxy server if your network administrator requires it (if you are a dial-up user, that would be your internet service provider or <acronym
>ISP</acronym
>). Otherwise, especially if you are feeling a bit confused about this proxy business, but everything seems to be fine with your internet connection, you don't need to change anything.</para>
